Industry focus centers on 541330 (Engineering Services) and 336413 (Other Aircraft Parts and Auxiliary Equipment Manufacturing), reflecting hands-on technical involvement in defense logistics, avionics support, and systems integration. The firm operates at the intersection of hardware sustainment and software-enabled supply chain solutions, positioning itself as a niche provider for rapid-response defense manufacturing and engineering task orders. Their work supports both legacy platform upgrades and next-generation sustainment architectures. As a small business structured as a 2L entity based in Arlington, VA, 540.CO LLC operates with agility and federal compliance rigor. While no formal certifications are listed, their consistent award history with DoD and GSA confirms demonstrated capability to meet stringent government procurement standards and deliver under complex contracting mechanisms.
